Aqua Feed Pellet Processing Overview
Aqua feed pelleting mainly refers to the processing techniques used in the production of aquatic feed. Depending on the feed type, pellet structure, and buoyancy/sinking properties, aqua feed machine typically employs two core processing technologies: extrusion or pelleting. These two aquatic feed processing techniques will be described in detail below.
Different types of aqua feed making machine
We offer a variety of aqua feed machine: dry extruders, wet extruders, and twin-screw extruders (for producing various aquatic and pet feeds, with a very wide range of applications); we also provide professional shrimp feed pellet mills equipped with a three-layer modulator, which significantly improves the ripening and water resistance of shrimp feed, suitable for both sinking and slow-sinking feed production. Whether for individual farmers or large-scale feed mill production, we can provide you with the most suitable solution.

Complete aquatic feed production process
Aquatic feed production is a systematic process, from raw material selection to finished product packaging, each step directly affecting the nutritional value of the feed. Below is a detailed introduction to the complete aquatic feed production process, from raw material reception to finished product delivery, helping you fully understand how professional aquatic feed is manufactured.
Aquatic Feed Production Process Flow Chart
The aquatic feed production process can be divided into three main stages: raw material pretreatment (cleaning and crushing), mixing and pelleting (ingredient formulation, mixing, conditioning, pelleting/expansion), and post-processing and packaging (drying, cooling, screening, and packaging). Each stage is interconnected, and a mistake in any link can affect the quality of the final product.

Frequently Asked Questions
What is the difference between a fish feed extruder and a regular feed pellet mill?
+
A fish feed extruder uses high temperature and pressure to puff the feed, producing floating pellets. This is suitable for observing fish feeding behavior, reducing waste and water pollution. A regular pellet mill, on the other hand, produces sinking pellets, which are denser and will sink to the bottom.
Extruded feed has higher digestibility and can withstand water for 12-24 hours, while sinking pellets typically withstand water for 2-4 hours. In terms of price, extruders require a higher initial investment than pellet mills, but produce feed with higher added value, making them suitable for the mid-to-high-end aquaculture market.
Should I choose a single-screw or twin-screw aquatic feed extruder?
+
Single-screw extruders feature a simple structure, lower cost, and a production capacity of 0.2–1 ton per hour, making them suitable for small-scale aquaculture feed production, pilot projects, and ornamental fish feed manufacturing as a practical aqua feed machine solution.
Twin-screw extruders are more expensive, but have a higher production capacity (0.5-12 tons/hour), better extrusion uniformity, and can process high-protein, high-fat formulations, making them suitable for commercial production of fish and shrimp feed and pet food.
If you are engaged in large-scale aquaculture or plan to sell feed externally, a twin-screw extruder is recommended; if it is for personal use and on a smaller scale, a single-screw extruder offers better value for money.
What types of feed can a fish feed extruder produce?
+
Fish feed extruders have a wide range of applications and can produce:
- Floating fish feed: Tilapia, grass carp, bass, salmon, etc.
- Shrimp feed: Through special molds and formulas, etc.
- Ornamental fish feed: Goldfish, koi, etc.
- Feed for turtles, tortoises, etc.
- Pet food: Cat food, dog food, etc.
By changing the mold with different aperture sizes (2-12mm), feeds suitable for aquatic species at different growth stages can be produced. Furthermore, by adjusting the formula and process parameters, the buoyancy, settling speed, and water resistance of the feed can be controlled to meet diverse aquaculture needs.
How to Choose a Reliable Aquatic Feed Production Line Supplier?
+
When selecting a supplier, consider these five aspects:
- Production Experience: At least 10 years of experience in feed machinery manufacturing, with a wealth of aquatic feed project case studies;
- Technical Strength: Independent R&D capabilities, able to customize solutions according to customer needs, and provide process technology guidance;
- Product Quality: Major components use high-quality materials (e.g., alloy steel for screws), and have quality certifications (ISO, CE, etc.);
- After-Sales Service: Provide installation and commissioning, personnel training, one-year warranty, lifetime technical support, and timely spare parts supply;
- Customer Reputation: Request to visit existing customer case studies to understand the actual operation of the equipment.
It is recommended to conduct on-site visits to the supplier’s factory to assess production capacity and management level. Price is not the only criterion; cost-effectiveness and long-term service guarantees are more important.
